To all 'whom it may concern:

Be it lrnown that l, FRANK Elo'U'ri-rwron, a citizen ot the United States, residing at lansas City, in the county ol lvl/yandotte and State ot liansas, have invented certain new and useiul linproveinents in 'llire- 'Llurning Devices, of which the following is a s} iecilication.

ln inany railroad repair shops it is quite coinnion, when a locoinotive is to have only ininor repairs, to j aclr up the locomotive and to heat the tires and rei'nove them troni the wheel centers. "lhen the tires are properlyT trued up in a suitable machine. This invention relates to devices adapted to he used in conjunction withwheel lathes tor the pur pose oit holding such deinounted tires 1n position so that they can he turned on a wheel. lathe inthe saine way that tires are ordinarily turned when mounted on their wheels. in accordance with the invention, provide supplemental tiro engaging hraclrets which are constructed and arranged to hold the tire so that it can he driven hy the ordinary driving,` devices. i

lin' the accompanying drawing, which shovvs the preferred,embodiment ci the invention, y

Figure l. a Yliront view showinga lathe lace lfilate together with the tire holding hraclrets and drivers.

Fig'. 2 is a iront view of the parts shown in Fig. l. l

Fig, 3 is a view somewhat similar to Fig. l hut eher-Jing a wheel and axle supported in the usual way hy the lathe center.

Figs. fl, 5 and 6 are detail lviews oi' the `tire engaging; bracket.

"ieterring to the drawing, l represents the tace plate olf a lathe lwhich inay he et any usual or preterred construction. lis shown, this lace plate is provided with radial "l slots Wfl The lathe is provided with a center 3 which ordinarily serves to engage the wheel axle and sinoport the wheel. and tire in position to he turned, as illustrated in lfig.

For driving the wheel and tire there are provided driving devices i of which any desiraliile or necessary nuniher may he provided. Ordinarily tour are used. tio fiar as i'ny invention is concerned, the details ot the drivers l may he changed, hut l prefer a construction similar' to that illustrated in Specification of Letters Patent.

Serial No. 330,331.

Patent 853,273 to Daniel itl. rleas for lathe driver. Y

ils shown in the said patent, and as herein illustrated, the driver comprises a trarne 5 which is adapted to he secured to the face plate hy nieans of one or more bolts 6 enter- 60 ing one ot the T-slots. Slidahly mounted in the slot in the iraine 5 is a serrated block 7 adapted to directly engage the side of the wheel or the tire. F or forcing the block 7 outward there is provided a screw 8 which 65 is 'threaded into the traine 5 and which engages the inner edge oit the block 7. lt will he seen that when the screw is turned the hloclr i' inay he inoved outward to torce the teeth thereoll against the wheel or the tire in such a way as to eilect a powerful driving action when the tace plate is turned.

ln order to engage the tire at the side opposite the tace plate l provide suitable hraclets whicl are preferably rigid in construction and wl'lich are adapted to hold the outermost `tace ot the tire at a fixed predetermined distance from the tace plate. Preferably in order to` utilize the saine drivers Li whiclrare ordinarily used for driv- .ing the wheel and the tire together, as shown in lfig. 3, l Ina 'te the tire engaging brackets supplemental to and independent of the drivers 1i. is shown generally in Figs. l and 2 and in detail in Figs. l to 6 the hraclrets 85 are indicated at 9. One et these brackets is lnounted adjacent each driver, being held hy holts l0 entering` the corresponding 'lV-slot in the 'face plate. Each hraclret 9 is preterahly rigid and it entends through the tire en and is provided with a lip il which is pret erahly iorined as a separate piece ot metal held hy holts l2. The lip is adapted to en ,gage the tire at the side opposite the tace plate. Preferably each Tcrachet 9 is pro- 95 vided with a suitable device tor engaging the inner surlace of the tire to assist in centr 'ing' it. its shown, each bracket has a i ew 1liior this purpose. lt will he seen that hy nicans et the several screws 13 on the respective brackets, the tire can he adjuster'. to central position. The several lips 1l serve ahutrnents for the tire to hold it in the saine position in which it would he held hy its wheel, as shown in Fig. 3. rlhe tire being thus held and centered hy the brackets, it is engaged hy the drivers which act exactly in the way already described to lll() Vmounted ones.

press the tire laterally againstV the said brackets.

lt will be seen that this construction makes it possible for the saine machine to be used interchangeably `for turning the tires on their wheels or demounted tires. No adjustment of the cutting toolsis necessary, and all that is needed to be done is to reverse the drivers, as indicated in F ig. l, and to put the several brackets 9 in place. The drivers can exert the samepowerful driving action which they exert where used in the usual'way, and just as heavy a cut can be taken on lthe demounted tires as on the inasmuch as the brackets engage the tires at the faces thereof which are opposite the face plate the tires are held in proper relationV to the cutting tools notwithstanding variations in the widths of the tires.

Vilhat I claim is:

l. The combination with a wheel lathe face plate, of a plurality of brackets secured to the iace plate and adapted to engage a tire at the side opposite the face plate and at a fixed predetermined distance therefrom, and a plurality of drivers carried by the face plate and adapted te engage V.the tire at the side adjacent the face piate and to press the tire laterally against the said brackets..

The combination with a wneel lathe face plate, of a plurality of brackets secured to the face plate and adapted to engage a tire at the side opposite the face plate and at a liXed predetermined distance therefrom, and a plurality of drivers seciiired to the face plate independently of the brackets and adapted to engage the tire at the side adjacent the face plate and to press the tire laterally against the said brackets.

The combination with a wheel lathe lace plate, of a plurality of rigid brackets secured to the face plate and adapted to en- ;jage a tire at the side opposite the face ,ilate anc at a i'ixed predetermined distance therefrom, means on the brackets for engaging the inner surface of the tire to center it, and a plurality of drivers carried by the face plate. and adapted to engage the tire at the sider adjacent the face plate and to press the tire laterally against the said brackets.

The combination with a wheel lathe face plate, oit a. plurality of braclmts secured to the face plate and adapted to engage a tire at the side opposite the face plate andv at a fixed predeterniined distance therefrom, means on the brackets for engaging the inner surface of the tire to center it, and a plurality of drivers secured to the face plate independently of the brackets and adapted to engage the tire at the side ailjacent the face plate and to press the tire laterally against the said brackets.

The combination with a whccl lathe face plate, of a. plurality of brackets .secured to the face plate and adapted to engage a. tire at the side opposite the face plate and at a fixed predetermined distance therefrom in the same position that it would occupy if in place on a wheel mounted on an axle and supported on the lathe centers, and a plurality of drivers carried by the face plate and adapted to engage the tire at the side adjacent the face plate and to press the tire laterally against the said brackets.

6. The combination with a wheel lathe face plate, of a plurality of brackets secured to the face plate and -adapted to engage a. tire at the side opposite the face plate and :it a 'lixcd pre(lctcrniiucd distance therefrom in the same position that it would occupy if in place on a wheel mounted on an axle and supported on the lathe centers, and a plurality of drivers secured to the face plate independently of the brackets and adapted to engage the tire at the side adjacent the face plate and to press the tire laterally `against the said brackets.

7. The combination of a tire supporting;r bracket adapted to be rigidly secured to the face plate of a wheel lathe, an outward projecting lip on the bracket adapted to cugage a tire at the side thereof opposite the face plate, and au outward j'irojectin;r s'acw in the body of the bracket adapted to cnthe inner surface of the tire to assist in centering it.

In testimony whereof l hereto allix my signature.
